. such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanyingdrawings, which forni a part of this specification.

This invention relates to sheaths for ve hicle wheels.

It has for its object an improved metallic sheathadapted to be secured over the rubber part of the pneumatic tire, andto protect the same.

It also furnishes a pegged tread enabling the Wheel to secure good tractionhold on the ground. l

In the drawings Figure 1, is a side elevation of the wheel protectedby the sheath. Fig. 2, is a longitudinal section of the sheath in straight form. Fig. 3, is a section'ofthe portionin the form it assumes when curved around the wheel. Fig. 4, is a cross section.

The sheath consists of a strip of metall, bent in a troughed or grooved form, and with the side anges slit at regular intervals from the edges 3 to the bottom of the' curve. l

The tread part 4 is left' unsevered. lVhen the metal is bent around the Wheel the edges of the slits 5 and 6 overlap, and to each'altornate section 7, 7, are secured by rivets or by some other way holding straps S and l), one of .which is provided With ar buckle or other suitable device, and the two straps on opposite sides of the wheel are brought together with the tire included between the bend of the straps and the buckles are drawn tight, thereby securing the entire sheath se- .curely to the wheel and tightening the engagenient of the overlapping flange portion to the edges of the adjacent portions which it overlaps.

of textile material, leather or rubber which is secured to the metal part of the tread by rivets 11, the outer end of which rivets are vleft large in the form of heads projecting beyond the textile leather or rubber part 10 of the sheath. The slits and G allow the curved sheath to yield as the'wheel turns preserving the utility of the flattened part of the tread which is immediat-ely in contact with the earth While protecting the tire itself from directcontact with the earth or articles upon the earth which might in- Vjure it, and also presenting the holding points 11 which may be renewed at small cost at any time, as also may the band l() of textile leather or vrubber material, which forms the actual tread surface of the assembled structure'.

What I claim is:

A sheath for pneumatic tires, comprising a tread ortion, and extended side flanges having sits cut therein, the portions inter- -vening between the slits alternately partially underlying and overlapping one auother, straps att-ached to each overlapping portion, adapted to engage about the -wheel rim, whereby the unstrapped portions are secured in close relation to the tire, and whereby such a connection isatforded as to render the sheath flexible when contacting with the ground, substantially as described.

In testimony whereof, I sign this specification in the presence of two Witnesses.
